The desk is a relic of a long gone director who had a back injury that prevented her from sitting for long periods. The new leadership wanted to trash it, but I insisted that we store it. A few months later, I learned of treadmilling at your desk and the light bulb went on! I traded my monolith of a desk in for a laughable dorm size desk (seriously, everyone truly laughs!) to sit beside the lift desk and purchased a tread from TreadDesk. The rest is history. I'm still trying to organize my office to find space for the files and folders I pulled out of the old desk, but I am LOVING the treadmill. My problem is pacing myself - but I'm working on it!
